Moondrop officially released the third-generation entry-level earphone "CHU 3", continuing the series' core concept of "high sound quality at a low price". The new product features comprehensive upgrades in appearance, driver unit, and tuning, aiming to further solidify its benchmark position in the entry-level market. [1]
The CHU series has been known for its high cost-performance since the first generation. CHU 2 already introduced aluminum-magnesium alloy diaphragm material. Based on inheriting this technology, CHU 3 optimizes the diaphragm suspension structure and uses more precise measuring instruments for tuning, striving to achieve acoustic performance closer to high-end earphones. [1]
CHU 3 is equipped with an aluminum-magnesium alloy composite diaphragm (aluminum-magnesium alloy dome + dual polymer suspension). The high rigidity and light weight of the dome enhance high-frequency extension and detail reproduction, while the dual-material suspension strengthens low-frequency dynamics and significantly reduces nonlinear distortion. Previously, such diaphragm materials were mainly used in Moondrop's high-end earphones and full-size headphones. [1]
In terms of tuning, Moondrop adheres to the principle of scientific tuning, combining advanced acoustic measurement systems with subjective listening for fine adjustments. The target frequency response curve of CHU 3 is based on the HRTF (Head-Related Transfer Function) PopAvg-DF (JM-1) standard. The company claims it features excellent high-frequency extension, three-dimensional soundstage, and naturally smooth timbre. [1]
CHU 3 further strengthens the "restorative" tuning style, making the frequency response closer to the target curve through precise adjustments. Compared to its predecessor, the new product improves soundstage positioning, imaging clarity, and timbre naturalness, while maintaining low distortion levels. [1]
As the newest member of the CHU series, CHU 3 brings diaphragm technology originally found in high-end products down to the entry-level price point, while continuing Moondrop's consistent scientific tuning philosophy. For users seeking high cost-performance and balanced sound quality, this new product offers a noteworthy new option. [1]
